BOILER-CLEANER.

SPECIFIGATION forming part of Letters Patent No. 511,064, dated December 19, 1893 Application tiled May 23, 1893. Serial No. $75,217. (No model.

To a whom it may concern:

Be it known that I, GOTTLOB F. SoHMI'D, a citizen of the United States, residing at Beardstown, in the county of Cass and State of Illinois, have invented certain new and useful Improvements in Boiler-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to certain improvements in boiler cleaners, and it has for its object to provide for the thorough removal of all sediment and mud therefrom and to return the water, withdrawn with the sediment, purified to the boiler, and further to provide for the application of the cleaner to several boilers at the same time for the cleaning thereof at one operation, and it consists of a series or battery of drums adapted for co-action and having pipe connection with the boiler at the water-lineand also steam pipe connection with the boiler, and means to return the water, entering the cleaner, purified to the boiler, also means to effect the connecsame time, all substantially as hereinafter more fully disclosed and pointed out in the claims. i

In the accompanying drawings: Figure 1 is a perspective view of my improved boiler cleaner. Fig. 2 is a similar view of the same with the multiple boiler attachment connected thereto. Fig, 3 is a perspective view of my invention as adapted for a locomotive boiler and for thrashing engine boilers. Fig. 4 is a detached view of the multiple boiler cleaner attachment.

In the embodiment of my invention, I employ a series or battery of drums A A A preferably three, two arranged horizontally and one vertically or endwise, which are preferably of varying capacities, the lower horizontal or bottom one, A, being the largest, the upright or endwise disposed one, A being next larger, and the upper horizontal one, A, being the smallest.

The lower horizontal or bottom drum, A, has, at one end, a blow-oft valve or cock, a, and has connection with a drum A, at its bottom by a short vertical pipe, b, and with the shown.

drum, A at its lower end or bottom by a not quite so 'shortrpipe, 0, provided with a. valve or cock, 0. The drums, A and A are also connected together by an elbow pipe, d, having its lower end connected to the drum or receiving chamber, A, near one end, and its upper end connected to the drum, A near its upper end.

The receiving or settling chamber or drum, A, at its opposite end, near the upper side, has connected to it' the lower horizontal end of a vertical pipe, e, provided with a hand wheel cook or valve, e, the upper end of this latter pipe being connected or coupled to a multiple boiler cleaner attachment, B, in case it is desired to apply the cleaner to several boilers for cleaning at the same time. Otherwise the upper end of the pipe, e, is connected directly to theboiler about at the water-line; and to the upper end of the return water chamber or drum, A is connected the lower end of a steam pipe,f, having also a hand wheel valve or coclgf', and connected, atits upper end, to the boiler at the steam space. Toa short vertical pipe, g, screwed into the upper end of the drum, A which may or may not have applied to it an oil cup,

g, is connected a return water pipe, h, also provided with a hand wheel valve or cook, h 8c The multiple boiler cleaner attachment, 13,

consists of a pipe, '1'), having one of its ends suitably closed by a screw plug, 19 and its other end provided with a nozzle, b adapted to be connected or screwed into the boiler as The pipe, b, is provided with several additional nozzles, b, all of which, and the nozzle, b are provided with hand wheel valves or cocks, b. v

- In Fig. 2 the apparatus or cleaner is shown as adapted for application to, andfor cleaning, a series of boilers, the multiple boiler cleaner being in position therewith.

In Fig. 8 the apparatus or cleaner is represented as applicable for cleaning locomotive and traction engine boilers, the tank, A, thereof being furnished at its ends with angular end plates or lugs, i i,toprovide for securing the apparatus in place upon the boiler. Said locomotive and traction engine cleaner or too apparatus is also provided with a pipe or union, 74:, to cut oil the same from the boiler this part or pipe, however, having its counterpart in the part or pipe, (1, of Figs. 1 and 2.

In operation, assn ming that the single boiler cleaner is being used, it will be seen that the sediment, mud, sludge, &c., in the water which, by the action of the steam or ebullition in the boiler, have been brought to the surface of the water, will be drawn toward, and find their escape through, the pipe, 6, by the action of the suction in said pipe, and enter the receiving chamber or drum, A, and separating and settling into the mud drum or chamber, A, the water going through the pipe,'d,

to the chamber or drum, A and the now 5 purified water passing from the chamber, A through the return pipe, h, to the boiler.

In the use of the multiple boiler cleaner, as in cleaning several boilers at the same time, the operation is obvious, the sediment, &c., being drawn from the boilers through their respective nozzles, 11 0 of the pipe, 1), into said pipe,whence said sediment, &c'., pass, as in the above described operation, into the pipe, 6, and so on. IVhen the sediment accumulated in the chambers or drums, A and A is to be removed, the valve, h is closed and the valves, 6 f, are closed half way, and the cock or valve, 0, is opened wide or full way, and the blow-off cook, a, is opened gradually. WVhile the operation is proceeding, produced by the above adjustment of the valves named, close the blow-oh? cock or valve, a, and the I steam cock or valve, f, and open wide the valves or cocks, c c and h, thus producing a circulation through the boiler and said chambers and pipes.

It will thus be seen that I secure an increased or extended traveling surface or area toeft'ectually precipitate the sediment in the cleaner, and also secure a continuous and direct circulation, providing a maximum suction for the thorough removal of the sediment, &c., from the boiler.

Ilclaim and desire to secure by ent- .1. In a boiler cleaner, a series or battery of Letters three pipe connected drums or chambers, the
